Question on odometer... Please read...

Ok well a little while ago my odometer stopped working because while fixing my speedo I broke the odometer gear. So anyway I got the new main drive gear and worm gear friday and installed them N/P. Then greased it all up with this silicone type grease. Anyway put it all back together and went for a drive around the block and it worked, put on 3/10's of a mile and parked it for the rest of the weekend. Then I went to drive it to the grocery store today and I noticed it didnt count any miles at all..... ... So I took it out thinking the new ones broke too or something and got pist, but when I took it apart it they where both fine. and there was just a part of the old worm gear in there and I took it out wiped off some excess grease and put it all back together. Went for a drive again and it counted up to 9/10's of a mile and stoped again...........

Any ideas? Kind of getting old constantly taking the cluster out and apart although I have it down to 5 minutes getting the cluster out and apart. But still it sux I want to see what my new mileage is with all the new o2's and 9mm wires.
